FULL-RANGE
AUTOMATIC TORQUE BOOST
Automatic control of V/f ratio according to the load
torque ensures tripless operation and optimum output
current . Therefore, tripless operation with excellent
energy-saving effect is available . When the
wiring
distance
between the
inverter
and motor is
long
(normally approx . 100 m) and when the motor torque is
a little short, increase torque compensation gain
gradually, checking
the motor current .
Normally,
no
adjustment is necessary .
Full-range
automatic torque boost
Motor torque requirement changes according to load
conditions . Full-range automatic torque boost adjusts
voltage of V/f pattern according to the requirement .
The VS-606PC3 automatically adjusts the voltage
not only during
constant-speed
operation but also
during
acceleration . Torque requirement is
calculated by the inverter .
